.scala,.sbt,.sc)Closes #10685
Implementation Details
.scala,.sbt,.scbuild.sbt,build.sc,.scala-build,project/build.propertiescs install metalsmetals(no arguments needed)statusBarProvider: "log-message",isHttpEnabled: trueWhy these decisions?
Coursier over direct binary download - Metals is distributed via Coursier (the Scala artifact manager). This is the official installation method and handles JVM version compatibility automatically.
Auto-download Coursier if missing - Follows existing patterns (gopls via
go install, csharp-ls viadotnet tool install). Coursier binaries are available for all major platforms.Java 11+ requirement - Metals requires Java 11 or later. The implementation checks for Java availability before attempting installation.
Project detection files - Covers SBT (
build.sbt), Mill (build.sc), Scala CLI (.scala-build), and SBT version file (project/build.properties).Files Changed
